We dry pailed and rinsed poopy diapers with a diaper sprayer hooked up to our toilet. We never had issues with this wash routine: We would wash on Hot with a full scoop of Tide and fill a Downy Ball with vinegar to be released in the first cold rinse. Then we would do a second cold rinse. Every 4-6 weeks we would add 1/4-1/2 cup of bleach to the wash.
Be sure you add your detergent & bleach to the washer as it is filling before you deposit your diapers. This dissolves the detergent better and dilutes the bleach. If you add detergent on top of clothes/diapers, it does not dissolve effectively.
